Once that visitor downloads your app, it will include our small SDK to fire events you define (such as "activation", or "in-app-purchase") that are tied back to the original visit. This allows you to see which external sites drive the best traffic and even calculate customer LTV for those web channels.

For targeted web, social or email campaigns we also provide you with shortlinks to extend conversion tracking down to a single tweet, email or a Google or Facebook ad unit.

Tapstream tracks over two million user events every day, for some of the great mobile apps you know and love.
